Perseus Mandate is the second standalone storyline expansion for F.E.A.R., in which you take point in a brand new team experiencing a new incident at Armacham with a story line that runs parallel to F.E.A.R. and Extraction Point (the first add-on), revealing a new perspective of the event. Your job in this new adventure is to find out what Perseus is and why the Nightcrawlers have been called in to collect it before you can.
